Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To improve reliability of connection by constituting an electrode wiring part to be connected to an element electrode, formed on a substrate from a wiring located within a vacuum vessel and a wiring located out of the vacuum vessel, and differing the sectional forms of the wirings located within and out of the vacuum vessel. SOLUTION: The sectional form of an electrode wiring 2 to be arranged within a vacuum vessel is set not in a rectangle form but in a gentle circular form having no angle, whereby discharge is hardly caused in the vacuum vessel. Therefore, the voltage can be increased, and an image of high contrast can be consequently provided. Furthermore, the reliability of an image display device is improved, and the productivity is also improved. Since an external load-out wiring 3 can be set rectangular, a wide contact area with a FPC 6 can be ensured to increase the number of grains of ACF 20, and the allowable current value can be increased in addition to the improvement in reliability of connection. Furthermore, since printing is used in the wiring part, cost can be reduced, and productivity can be improved.

IPC: B05C1/08
Filed: 1980-04-10
Abstract: PURPOSE: To automatically and continuously control the thickness of a coating film with high accuracy by a thickness detector utilizing the permeance of radioactive rays or the like, and to control the thickness of the coating film at a constant value by the feed-back of the detected value.  
     CONSTITUTION: A couple of thickness detectors 5 are arranged at the backside and the frontside of a coating zone 2, 3, 3' in a coated steel sheet-making plant. One detector 5 detects the thickness of a naked steel sheet 1, while the other detector 5 detects the thickness of a coated steel sheet, i.e. the sum of the steel sheet 1 and a paint film 4. Both of the detected values are inputted to a signal processor 8, where a desired paint film thickness is computed on the bases of the detected values. The obtained paint film thickness is compared with a reference thickness value which is previously inputted to the processor 8. The processor 8 outputs the deviation as an operational signal for a film thickness controller 9. Consequently, the film thickness controller 9 is operated to control the thickness of the paint film.

Title: Optical demultiplexer/multiplexer
Inventor: KITAHARA TOMOYUKI
IPC: G02B6/34
Filed: 1981-04-01
Abstract: PURPOSE:To obtain an optical demultiplexer/multiplexer for multiplexing of  wavelength having excellent cross talk properties, by combining a short wavelength pass filter and a long wavelength pass filter at the front of a coupling  lens of transmitting and receiving elements. CONSTITUTION:The light of a short wavelength lambda1 passes through the short wavelength pass filters (SWPF) 2 and 1 via a rod lens 4 from a light emitting element and then enters an optical fiber transmission line 13 via a rod lens 5. The light of a long wavelength lambda2 sent from the line 13 is reflected by the SWPF1 and passes through a long wavelength pass filter (LWPF)3 and enters a photodetector via a rod lens 6. The wavelengths lambda1 and lambda2 plus the SWPF and LWPF are exchanged with each other between the SW type of the long wavelength reception and the LW type of the short wavelength reception. The LWPF1 and SWPF9 that cut the light lambda1 and lambda2 respcetively are provided at the front of rod lenses 3 and 11 respectively for both SW and LW types. Thus the excellent cross talk properties can be obtained for an optical demultiplexer/ multiplexer for multiplexing of wavelength.

Title: Static image forming device
Inventor: NAKAO HIDEYUKI
IPC: H04N1/405
Filed: 1988-03-02
Abstract: PURPOSE:To allow a high-quality intermediate tone image to be obtained without stripes in subscanning and vertical directions by increasing dots preferentially in a subscanning direction of light-emitting diodes, forming a matrix dot pattern and changing an exposure intensity in accordance with an exposure time. CONSTITUTION:Image density data which is output from a buffer part 1 is converted to a matrix dot pattern by ROM 3. At that time, a recorded part in a matrix increases dots preferentially in a subscanning direction, and connects with the recorded part of an adjoining matrix in a subscanning direction. Consequently, the area ratio of the recorded part and the unrecorded part does not change easily, if the rotating speed of a photosensitive drum changes, and generation of stripes in the subscanning and vertical directions of an output image is prevented. The reproduction of even small dots in a stable condition is possible by controlling the exposure time and intensity per dot of a laser beam, increasing the exposure intensity in proportion to a decrease in the exposure time, and allowing sufficient energy to be implanted into a photosensitive drum.

Title: Ignition timing control device for internal-combustion engine equipped with knocking control unit
Inventor: DAIMON TERUMI
IPC: F02P5/153
Filed: 1981-03-30
Abstract: PURPOSE:To improve responding properties for knocking by a method wherein the amount of delay angle in a revolving area below predetermined under accelerating and decelerating conditions as well as the amount of advanced angle after the control are varied in a big amount by the control device delaying the ignition timing in accordance with the output of a knocking signal. CONSTITUTION:In a low-speed revolving area, a transistor T0 is being put ON, therefore, the same T2 is being put OFF. Upon acceleration of the engine, VC vacuum is descended and the output from a vacuum switch 12 becomes high, therefore, the transistor T6 is put ON. When the transistor T1 is being put ON, the value of a constant current becomes small and the descending rate of the output of an operation amplifier OP1 becomes small while the transistor T1 is being put OFF only when the engine is rotating under a switching revolving number under a high output, therefore, the descending rate of the output of the operation amplifier OP1 becomes high only when the engine is accelerated suddenly in the low-speed area. On the other hand, a current i2 becomes larger than the same i1 in the low-speed area, therefore, the delaying amount of the ignition timing becomes large. In a middle and high-speed area, the transistor T2becomes non-operative and the current i2 becomes small, therefore, the delaying amount of the ignition timing is not so large as the same in the low-speed area.

Title: Improving method for corrosion resistance of nickel maraging steel
Inventor: SUEDA MINORU
IPC: C23C8/18
Filed: 1978-04-24
Abstract: PURPOSE:To enhance the corrosion resistance of nickel maraging steel to UF6 gas and to prevent the leakage rupture, etc. by heating the steel in a CO2 gas atmosphere at a specific temp. to form an oxide film on the surface. CONSTITUTION:18% Nickel maraging steel is surface cleaned by ultrasonic washing or the like and heat treated in a CO2 atmosphere at 450-550 deg.C to form an oxide film which has very good corrosion resistance and does not undergo corrosion even in a UF6 gas atmosphere. Occurence of troubles such as hydrogen rupture is prevented which is due to residual hydrogen in steel treated with superheated steam. The oxide film is dense and has good adherence to the base metal. When the steel is heated at above 550 deg.C, the strength is lowered remarkably. In case the heating temp. is below 450 deg.C, the resulting oxide film has good corrosion resistance but predetermined mechanical characteristics can not be held.
